Ever since the invention of the laser more than 50 years ago, scientists have been striving to create an X-ray version. But until recently, very high power levels were needed to make an X-ray laser. Making a practical, tabletop-scale X-ray laser source required taking a new approach, as will be described by physicist Margaret Murnane in this fall’s Hans Bethe Lecture.
Tabletop coherent EUV/SXR beams are now possible using high-harmonic generation (HHG).1,2 In addition, a new generation of powerful coherent-diff ractiveimaging (CDI) techniques is removing the resolution limits imposed by traditional X-ray microscopy, by replacing lossy and imperfect X-ray optics with powerful iterative phase retrieval algorithms.
Franklin Dollar, a member of the Dry Creek Band of Pomo Indians in California, was a 2012 Research Experiences for Undergraduates (REU) student at the NSF’s now-graduated Extreme Ultraviolet Engineering Research Center (EUV ERC), based at Colorado State University. Now, as a faculty member at the University of California at Irvine (UCI), he is one of the faculty participant enablers in NSF’s newly formed STROBE Science and Technology Center (STC).
The physical lens had been the standard for use in the detailed study of microscopic organisms since Hooke’s seminal work Micrographia was published in 1665. Dr. Jianwei Miao, a professor of Physics and Astronomy and the California NanoSystems Institute at UCLA, blew that standard out of the water with a method known as Coherent Diffractive Imaging (CDI).
In recent months, one company after another has come out with products that appear to create holograms—but according to optics experts, most do not use true holography to create their three-dimensional (3D) effects.
Plenary wrap up with Dr. Laura Waller, University of California Berkeley. Computational Microscopy for High-Throughput Science
Berkeley Lab researchers help to map iron-platinum particle in unprecedented detail.
Researchers measured the coordinates of more than 23,000 atoms in a technologically important material
The Science and Technology Center on Real-Time Functional Imaging, known as STROBE, will be headquartered at CU Boulder and integrate several areas of imaging science and technology, including photon and electron-based imaging, advanced algorithms, big data analysis and adaptive imaging.
Franklin Dollar was born on the wrong side of the digital divide.
“I’m a member of the Dry Creek Band of Pomo Indians,” he says. “I grew up on a small reservation near Geyserville, California, with no running water, no electricity and no internet access.”
